Every side will play a total of eight games in the league phase, with the top eight progressing to the last 16 and those ranked ninth to 24th in the table taking part in a play-off.
Every game will matter in the race to avoid an early exit and the standout fixture on the first matchday is a repeat of the 2023 Champions League final as Manchester City face Inter.
The number of matches shoots up from 125 to 189 as a result of the changes, which means there is a lot more Champions League football to savour this season.
